To all whom it may concern:

BURGER, a citizen of I siding at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Bottle-Capping Machines, of which the following is a specislots 14 fication.

The primary object of this invention is to provide a rotary cappin idly and effectively appl ying caps to milk and cream bottles.

A further object of the invention is to provide bottle capping means adapted to be.

automatically operated by the bottles as thev are discharged from a filling-machine. h In the accompanying drawings F igure 1 1s a plan view of the invention. Fig. 2 is a detail view, partly in section. Fig. 3 is a sectional view on the line 33 Fig. 4 is-a detail enlarged sectional view.

machine for rap-' Fig. 5 is a sectional view on the line'5-5 of I Fig. 3. Fig. 6 is a sectional 6-6 of Fig. 3.

Referring to the drawings, 7 is a table which is supported on a standard, 8 and is view on the line located alongside of a bottle filling machine. This table constitutes the discharge table of I the filling machine and it is provided with walls 9 which form a ceive the bottles 11 from the bottle rests 12 on the filling machine. 13 are mounted in bases 14 on the table 7 and each base is adjustably secured on the table by a bolt 15. The bases have radial and the table has a plurality of curved slots 7 to receive the bolts 15. these slots being arranged in such relation to each passage-way 10 to rei l I l E that each cap opening 20 will receive a cap Be it known that l', FRANK O. H. STRAS- i the United States. re

from one of the magazmes'as the plate is reery plate will take the caps first from the first magazine and then from the second and so on and the plurality of magazines provides for av large supply of caps so that. the machine can be operated uninterruptedly until all of the caps are exhausted. The n'iagazines canobe filled while the machine is in operation and if for any reason the delivery plate fails to take a cap from one magazine it may take one from the next magazine. The stacks of caps rest upon the delivery plate and when a cap 1s seated in one of the openings it will lie flush with the upper surfaceof the plate and slide under the succeeding magazines without disturbing the capstherein. The vertical shaft 18 also carof 1. I

rl'es one or more star wheels to engage the bottles. In the drawings I have shown an upper star wheel 21 to engage the neck of the bottle and a lower star wheel 22 to engage the body of the bottle, both star wheels being rigidly mounted on the shaft 18. The table is provided with a circular wall 23 forming an opening 23 to receive the revolublehlock 24. This block projects laterally above the upper edge of the circular Wall 23 and is provided with a ball bearing 24 on E said wall. A plurality of posts 7 The block 24 carries a star wheel 25 which engages the body of the bottle and is located opposite the star wheel 22. A verother as will permit of the proper adjnst ment ofthe posts for the purpose hereafter described. mounted on each post adjusted position by a set screw 16. Each collar carries a magazine 17 which may be in the form of a cylinder, as shown, of a size adapted to receive a stack of bottle caps.

A vertical shaft 18 on the table 7 and a rotary delivery plate 19 is rigidly mounted on per end thereof. This delivery plate is provided in its periphery A .collar 16 is adjustably 13 and is secured in The shafts 18 and 26 carry gears 18 and 26 at their lower ends which mesh with each other so that the shafts and star wheels will operate in unison. The revoluble block 24 also carries a plurality of cappers each of which comprises a rod 28 movable vertically is revolubly mounted in the block and carrying an arm 29 to which a head 30 is secured preferably by a; ball and socket joint 31. A spring 32 is arranged on each rod 28 between the star wheel 27 and a i collar 33. A roller 34; is arranged at the this shaft at the upi lower end of each rod to travel on a cam track provided around the shaft 26 on an with a plurality of openings 20 having bevel edges 20. The I magazines are arranged w1th their lower dis- 5 charge ends just clear of the upper surface of the delivery plate and in such position arm 36 mounted on the standard 8.

The number of cappers is equal to the number of cap openings in the delivery plate and Z to the sockets in the star wheels and they are arranged in cooperating relation so that 2 eaaaei when a bottle is located in capping position, a cap will be supported by the delivery plate immediately above the mouth of the bottle and a oapper head will be located immediately above the cap. The cam track has an abrupt step and when the bottle, cap and head are thus arranged the roller 84 will travel oil of the step and the spring will move the capper rod downward with a quick motion and with suihcient force to cause the capper head to disengage the cap from the delivery plate and force it to its seat in the month of the bottle. This operation is repeated as fast as the bottles move into capping position and it will he observed-that all of the movements are automatic and are induced loy the movement oi, the bottles. in the mod-em filling machines the bottles automatically discharged on to a table and push each other along a passage-way thereon, I arrange the table 3 so that the bottles may be discharged from the filling machine intothe passage-way l0 and each bottle is pushed by the next bottle along said passage-Way until it is engaged by the star heels and registered thereby in capping po- Jnion. he movement of the-bottle is suhstantially continuous and hence I provide a step 35 on the cam and a strong spring on the capping rod to operate the capping head quickly. Iprefer to provide that part of ,the table over which the bottles travel with ribsif? so as to reduce the friction of the bottles on the table.' 1
